High persistence (environmental degradation half-lives of several years or more) has important implications for the behavior of chemicals in the environment. Persistent chemicals are distributed widely, often globally, and reach (much) higher concentrations than short-lived chemicals emitted at the same rate. We illustrate these features of highly persistent chemicals using a unit-world environmental fate model. Over the last decades, persistent chemicals such as polychlorinated biphenyls and poly- and perfluoroalkyl substances have caused serious impacts on the environment and human health. We argue that high persistence should be given particular emphasis in chemicals assessment and management and that highly persistent chemicals should be regulated on the basis of their persistence alone (P-sufficient approach)

The World

Development and civilization have been top-rated priorities and indication of human success in the world; and the largest segment of world talent are immersing to mark new and ever un-experimented record in this course. But paying more attention towards money centric gain and material prosperity centric civilization, an irrational attack on environment is rife everywhere. In last few decades, the environmental strength of world has been largely damaged and it has offered severe impacts on human health now. Though, people were more over-swayed with anthropomorphic use of environment and some transitory progress gained, slowly the imbalance of environment and its reverse effects on human lives have started taking limelight of people. And now, environment seems to be equally pressing and compelling agendas of human checklist to do. If not initiated anything great, it may be more than late to save us and future generation. Thus, the article tries to disclose the impacts of environmental degradation and urges to have efficient actions to alleviate the situation with acknowledging and accessing few of initiatives taken, here so forth.

Abstract Dioxin-like polychlorinated biphenyls (DL-PCBs) are a class of persistent toxic substances with a high potential to accumulate in the soil as an organic pollutant and bioaccumulate in humans. The study determined the level and human health risk of twelve (12) DL-PCBs in soils from mechanic workshops within Nekede mechanic village (NMV), Imo State. In this study, soil samples (0–15 cm depth) were collected at four different sampling points within Nekede mechanic village. At each sampling point, composite samples consisting of 10 sub-samples were collected with pre-cleaned pet bottles using soil auger and were labeled SA, SB, SC, SD. Control sample was taken 500 metres away from the mechanic village where there was no form of auto-mechanic activities. Sample analysis was conducted using Agilent GC 6890N coupled with Agilent MS 5970B to determine the levels of DL-PCBs. The data were analyzed using SPSS version 23. The results revealed that the mean concentration of 12 DL-PCB congeners (Σ12PCBs) in soil ranged from 0.31–16.31 µg kg− 1, which was much higher than that in the control sample (0.006–0.087 µg kg− 1). PCB-126 was the major contributor (58.99%) while the least contributor was PCB-157 (0.0040%) of the Σ12 DL-PCBs TEQ. The estimated LCR (adults 1.29×101, children 4.42×101) and HQs (adults 6.68×102, children 2.29×103) were above the acceptable risk limit (LCR = 10− 4, HQ = 1); indicating a very high adverse effect of DL-PCBs on humans especially children.

The Impact

When natural habitats are destroyed or natural resources are depleted the environment is degraded. Environmental degradation results from factors such as urbanisation, population growth, intensification of agriculture, rising energy use and transportation, climate change, pollutions arising from many sources such as technological activities. It is explored that as a result of the dynamic interplay of socio-economic factors and technological activities amongst many other factors, these have devastating consequences on human health. Thus environmental degradation consequences affect the health and the right to health of the people. Using the doctrinal method of research, we examine the confluence of environmental degradation and health from a rights perspective. An unhealthy environment possess health hazards consequently a violation of the right to health. The article recommends that states’ obligation under international law to protect the right to health should be enforceable. Human beings are entitled to right to health even as the environment needs to be protected from activities which cause environmental degradation.
